Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to a heat insulation structure of a weighing sensor. Background Art

[0002] At present, in the thermal radiation environment (such as kitchen stoves or gas stoves, ovens, microwave ovens, rice cookers, steamers, soybean milk machines, food processing production lines, etc.) and refrigeration equipment environment (such as refrigerators, refrigerators, cold storage, etc.), since the sensor housing is mostly made of metal castings, heat conduction or cooling is relatively fast, which will cause the strain gauge of the weighing sensor in the housing to have too large a temperature difference in a short time, resulting in temperature drift of the sensor output signal. Even if the output signal is processed secondary, the deviation is still large.

[0003] After consulting the literature, it is learned that the currently published patent: CN217930517U discloses the thermal insulation structure of the weighing sensor, which belongs to the technical field of weighing sensors. The key points of its technical solution include the weighing sensor body, which includes a shell, which effectively prevents the weighing sensor from being damaged or the accuracy is reduced due to collision. The upper end of the strain gauge is fixedly connected to the loading end, and the fixed end will not tilt or rub, ensuring that the force will not change, thereby improving the accuracy of the output weighing signal.

[0004] However, this solution will also cause the following problems during use: since there is no cable storage structure in the device, the sensor output line in the device is directly exposed to the external environment, so that when the sensor is transported, the sensor output line is easily squeezed by objects in the external environment, causing damage to the sensor output line and reducing the convenience of sensor transportation. In view of the above situation, technical innovation is carried out on the basis of the existing device. Utility Model Content
